There is a floor beneath your feet, but you don’t experience the floor directly; you see the light reflected from the floor, or rather, you see what your retina and visual cortex have processed of that light
 

But indeed, I experience the floor directly; the experience of the floor is not limited to visual perception but also involves direct sensory inputs. The sensation caused by gravitational pull and the counter-pressure from the floor are experienced directly. Additionally, the sound produced when stepping on the floor and the anticipation of the floor's existence contribute to the direct experience of the floor. Therefore, the floor is experienced directly through a combination of sensory inputs, including but not limited to, visual, tactile, auditory, and proprioceptive sensations.
